IdtSNDE-class {MAINT.Data}

Class "IdtSNDE"

Description

IdtSNDE is a class union of classes IdtSngSNDE and IdtMxSNDE, used for storing the estimation results of Skew-Normal modelizations for Interval Data.

Methods

coef

signature(coef = "IdtSNDE"): extracts parameter estimates from objects of class IdtSNDE

stdEr

signature(x = "IdtSNDE"): extracts standard errors from objects of class IdtSNDE

vcov

signature(x = "IdtSNDE"): extracts an asymptotic estimate of the variance-covariance matrix of the paramenters estimators for objects of class IdtSNDE

mean

signature(x = "IdtSNDE"): extracts the mean vector estimate from objects of class IdtSNDE

var

signature(x = "IdtSNDE"): extracts the variance-covariance matrix estimate from objects of class IdtSNDE

cor

signature(x = "IdtSNDE"): extracts the correlation matrix estimate from objects of class IdtSNDE
